WEFT CHECK OR DRAG FOR LOOMS.

SPECIFICATION forming partof Letters Patent No. 355,804, dated January 1 1, 1887. Application filed January 26, 1885. Serial No. 153,954. (No model.)

To all uihmnit may concern.-

Be it known thatI, SAMUEL S. WALKER,

of \Varren, county of Bristol, State of Rhode Island, have invented an Improvement in Weft Checks or Drags for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The object of this invention is'to provide a device or drag to prevent injurious kinking of the filling or weft thread between the shuttie-box and the selvage of the cloth being woven.

To obviate the difficulty referred to I have provided the lay at its front side, between the selvage ofthe cloth being woven and the shut tle-box, or between the latter and the reed, with a filling or weft check or drag composed of a backing provided with a friction-surface for catching and holding the weft, the backing being preferably of leather and the frictionsurface a piece of cloth placed on it.

Figure 1 shows in front elevation a suffi-- the lay, between the reed and the inner end of the shuttle-box, I have attached my improved filling or weft-check D, herein shown as a rather stiff piece of sole-leather, 2, for a backing, and faced with textile material, as at 3, for the friction-surface.

When weaving, the weft or filling thread, extended from the selvage to the shuttle, is 40 apt to become kinked or twisted, and fre quently the shuttle when thrown into the shed fails to pull sufficiently upon the weft or filling to straighten out the twist or kink. I effectually overcome and obviate this difficulty 4 5 by the employment of the described threadcheck extended upward above the race of the lay and having a friction-surface against'which the weft or filling thread catches,and by which it is held back or retained with sufficient friction to obviate the formation of kinks or twists in the thread.

I claim The lay having the usual reed and sh uttleboX, combined with the filling or Weft check or drag D, composed of the stiff backing and the frictionsurface thereon, and arranged between the end of the reed and the shuttle-box to act upon the shuttle-thread and prevent it from kinking when the shuttle is thrown into the shed, substantially as described.

In testimony whereof I havesigncd my name to this specification in the presence of two subscribing witnesses.

SAMUEL S. \VALKER.
